Plants can acquire an improved resistance against pathogen attacks by exogenous application of natural or artificial compounds. In a process called chemical priming, these compounds causes earlier, faster and/or stronger responses to attacks. The primed defense may persist over stress-free time (lag phase) and be expressed also in plant organs that have not been directly treated with the compound. This review summarizes current knowledge on signaling pathways involved priming Chemical induced systemic (ISR) acquired (SAR) is highlighted. roles transcriptional coactivator NONEXPRESSOR OF PR1 (NPR1), key regulator immunity, (IR) salicylic acid during are underlined.

Soil salinization adversely affects sustainability and productivity of cultivable land by altering seed germination, growth physio-biochemical attributes consequently limiting agricultural output. To sustain crop productivity, therefore, the need to comprehend plant tolerance mechanism becomes imperative. Enhancement stress resilience can be achieved through several methods but here, we delineate a novel cost-effective ecofriendly technique known as priming, which involves pre-germinative exposure seeds eliciting factors that induce mild fortifies plants against subsequent stressful constraints. Priming sensitizing in different chemicals prior sowing enhances its imbibition capacity metabolic processes improve seedling emergence, growth, vigor productivity.

Volatile organic compounds (VOCs) produced by potential plant growth-promoting rhizobacteria (PGPR) play an important role in interactions. However, the mechanisms underlying this phenomenon are not well understood. Our findings show that influence of VOCs from PGPR strain Bacillus vallismortis (EXTN-1) on tobacco growth is dependent culture media used.
